" H ADLIGHT ATTACHMENT.

Application filed August 11, 1926. Serial No. 128,674.

This invention relates to improvements in co-pending application forheadlight attachments, Serial No. 63,240, filed Jan. 23, 1926. i

The main object of the present invention is to provide attachments forheadlights of the bullet type which will permit the radiation oflightlaterally to the roadsides and at the same time eliminate thedirect rays to approaching drivers. I

More specifically, thev invention includes a detachable shell designedto be positioned within the conventional headlight of the typementioned, which shell contains aplurality of vertical partitions forpreventing the lateral diffusion of the light rays, the partitions alsobeingprovided with cutout portions for permitting the escape of-certainlight rays through lateral ports in the walls of the lamps proper.

Reference will be had to the accompany ing drawings forming a part ofthis specification and wherein like characters of reference designatecorresponding parts throughout the several views in which Fig. l is aside elevation showing a portion of a motor vehicle, in elevation, withthe lamp attached and the method of projectng the light to thefront andside of the roa Fig. 2 is a top plan View of Fig. 1.

Fig. 3 is a sectional view through one of the lamps showing the shellwith the partitions in position, the rays being directed through one ofthe lateral parts, and

Fig. 4 is a front view of the lamp cut in two on a horizontal plan withthe halves separated showing the location of the ver tical partitions,the openings in the lower side and certain partitions with parts of themcut away to permit the unobstructed passage of the light F.

Referring to Figs. 1 and 2; a motor vehicle is illustrated sufficientlyto show the position of the lamps and the direction of the forward andlateral rays therefrom. In these figures reference characterAillustratesthe radiator, B, the wheel, and C, the fender of a vehicle. The lampsare illustrated by reference character E and disclose forward beams oflight G and lateral beams, F. The lamps, which-as heretofore statedareof the conventional bullet type, includes a lamp casing a, and a forwardchamber 1;, which latter is adapted to contain the series of verticalpartitions hereinafter described.

In the lamp chamber a, the globe is illustrated at d, and a reflector i,is positioned rearward thereof to project the-light through the lamplens e. The shell b is provided'at one side with a lateral opening g,locatedsutficiently near the base from the lamp d tolbe approximately atthe edge of the conventional road. i

It will be well to note here that inoutfitto permit the rays ting amotor vehicle with the present type of lamp, it is usually advisable toprovide projected at points one lamp with the lateral opening 9 to the aright and another lamp with the lateral opening 9 to the left, wherebythe raysfrom the lamp through the openings will be pro jected to eachside of the road. In some instances it may be preferred to only equipthe right-hand lamp with a righthand opening, observe only his side ofthe road. This selection of lamps, withthe respective openings, ismerelya matter of choice anddiscretlon with the operators; The lamp properincludes a casing a, in which is located the globe d and the reflector2', which latter is positioned to the rear of the globe. The lens e ispositioned sufficiently rearward of the outer peripheral edge of thelamp shell a to permit the arrangement of the threaded portion f, bymeans of which the forward body or the shell 6 is attached. The shell I)is of a generalcylindrical form gradually reduced at either end topresent a neat appearance at the points of junction with the lamp a, andalso at the forward end through which the rays are projected. Within theshell b are arranged a series of vertical partitions of various designsa suitably spaced and extending longitudinally from end to end of theshell body. These partitions prevent a lateral filtering of the rays andcause whereby the driver can a forward projection in a direct line andout (1 may filter through the lateral openings g, the partitions in thatside of the shell 6 adjacent the openings are cut away, the cutoutportions gradually increasing to accommodatethe gradually increasingraysfrom the lamp.

It will be noted that the vertical partitions in that half of the lampadjacent the opening 9 are cut away as at h, each part-ition beginningat the one adjacent the center partition being gradually cut away to agreater extent to accommodate the en arged light area from the lampthrough the open- Ille present invention is designed with the idea thatsame may be attached to the usual type of lamp, converting same into abullet type of lamp, and also adding thereto the advantages of theprotected forward rays and the lateral rays. In the event that thedevice is used as an attachment for the ordinary lamp, it will beobvious that same could be attached by utilizing a threaded ring whichmight be attached to the lamp body by any suitable means, the attachmentbeing threaded thereto. In the event that an ordinary lamp is notconverted into the present form, an entire lamp is manufactured as aunit, the sectional construction comprising a lamp chamber a and a shellb will permit the removal of the lens e for the arrangement of a newglobe or for the adjustment of a reflector. If desired, the chamber aand the shell 12 could be made in one piece with the vertical partitionsa re-a5 movable from the shell and the lens 0 held in place by anysuitable means.

What I claim as new and desire to secure by Letters Patent, is

1. A lamp includin a body provided with a source of light an sionconnected to the body outwardly of said lens, said shell extensionhaving an opening in its wall, and partitions in said shell extensioncoinciding in len th with the latter, only such portions of t epartitions positioned in the line of travel of the light rays from theirsource to the lateral opening being cutaway in varying amounts, whichprogressively increase as they approach the said opening, to permit thepassage of light through the opening.

2. A lamp including a body provided with a source of light, a shellextension connected to the forward end of the body, such shell extensionhaving an opening in its wall and intermediate its ends, and partitionsin said shell extension having their rear and front edges terminating onlines dis osed at right angles to the longitudinal axis of the shell Iextension, such portions of the partitions positioned in the line oftravel of the light rays from their source to the o ening in the wall ofthe shell extension being cut away to permit the passage of lightthrough the openlng.

In testimony whereofI aflix my signature.
